Introduction

Section 1: Introduction

1.1 DO

1. Do follow proper storage procedures. Improper storage will void warranty.

2. DANGER: Do check for proper motor rotation. If valve goes in the wrong

direction when button is pushed, you have no torque or limit protection. Either

incoming power or motor wiring must be reversed.

3. Do read and follow procedures before attempting to energize actuator.

4. Do cut off electric power before opening switch compartment.

5. Do install pressure relief vent in highest point of gearbox.

6. Do use stem covers of sufcient length to protect valve stem.

7. Do clean Electrical Enclosure flange thoroughly & lightly grease before closing.

8. Do secure all Electrical bolts.

9. Do follow an annual maintenance procedure.

10. Do use caution when working on, with, or around valves and actuators. You are

dealing with high pressures, forces, voltages and ammable or toxic media.

1.2 DON'T

1. Don't Start-up without reading this manual.

2. Don’t stack actuators.

3. Don’t store actuator on the ground unprotected.

4. Don’t lift the unit by clutch lever or handwheel.

5. Don’t lift a valve assembly by electric actuator.

6. Don’t operate electrically without rst checking for proper phase rotation, valve

position, torque and limit switch adjustments.

7. Don’t plug the motor by starting and stopping repeatedly to move a valve that is

too stiff. Check for cause.

8. Don’t jumper torque switches except as recommended by Wiring Diagram or

Valve Manufacturer.

9. Don’t use oversize thermal motor overloads to eliminate a tripping problem.

Find the cause and correct.

10. Don’t use a cheater to try to force the handwheel. You can damage gearing and

shafting. Find the cause and correct.

1.3 Lubrication

BETTIS actuators are factory lled with a high quality lubricant carefully selected to ensure

actuator performance under specied operating conditions. Refer to BETTIS JOB SPEC

SHEET to identify the lubricant provided. Normal operation of actuator may not require

replacement of lubricant.

Section 1: Introduction

Introduction

1.4 Maintenance

At least once a year a check should be made of your BETTIS actuator.

a) Disconnect all electrical power to actuator.

b) Open Electrical Enclosure. Inspect and tighten all electrical connections.

c) Visually inspect for any electrical or mechanical damage. Replace worn or

damaged components.

d) Check lubrication consistency and level. Fill or replace if required.

1.5 Pressure Relief

During normal operation of Electric Actuator, gear temperature increase in combination

with outdoor temperature variations will cause a small pressure build-up. BETTIS furnishes

a Pressure Relief Vent Fitting P/N 83385. Placement on Actuator can be determined only

after eld location and position of valve has been determined. Select the highest 1/2 NPT

vent location in the Gear Box, remove 1/2 NPT Plug and replace with P/N 83385. Possible

locations of the Plugs are shown on BETTIS Outline Drawing.

1.6 Short Term Storage

1. Actuator should be stored in the recommended mounting position. The motor

should be horizontal and Electrical Enclosure either horizontal or vertical.

Figure 1

2. Actuator should be stored indoors free from job site dirt, mud, moisture and

temperature changes.

3. If indoor storage is not possible, the actuator must be stored off the ground, above

possible water or snow level. Remove MCP and store with other electrical and

electronic equipment in protected warehouse. If MCP is not removed, Space

Heater MUST be energized to protect Electrical and Electronic Controls.

Introduction

4. BETTIS supplies plugs in each conduit entry. Do not remove until electrical

hook-up.

5. Cover units loosely with a plastic sheet. This serves as partial protection from rain.

1.7 Long Term Storage (Stored more than one year

from shipment)

1. Store indoors or MCP must be removed and stored in protected area. Follow

procedures of short term storage.

WARNING:

FAILURE TO STORE ACTUATOR PROPERLY WILL VOID WARRANTY OF ELECTRICAL &

ELECTRONIC COMPONENTS

M2CP Electrical Hook-Up

Section 2: M2CP Electrical Hook-Up

Remove PWR and TBM covers to expose terminals for customer wiring. BETTIS Modular

Modular Control Package (M2CP) is available congured in many combinations of electrical

and electronic parts. Refer to WIRING DIAGRAM and BETTIS JOB SPEC SHEET for

components provided by BETTIS. Connect control wires to TBM and Power (motor) Voltage

to PWR terminals. If optional M2CP mounted circuit breaker was specied, connect power

voltage leads to circuit breaker. BETTIS terminal blocks are furnished with wire binding

screw connectors with rising captive plates, allowing eld connection by several methods:

1) strip and connect bare wire, 2) strip and install wire ferrule, 3) strip and install crimp-on

insulated or non-insulated ring tongue or similar terminal. Circuit Breaker accepts 1) bare

wire strip, or 2) wire ferrule.

Figure 2

2.1 Electrical Hook-Up

1. STEP 1. Move valve to mid-position by handwheel. This will allow sufcient time

to stop actuator in case of improper hook-up or reversed incoming power voltage

phases.

2. STEP 2. Identify a means of removing power from actuator during check out.

Be sure no erroneous remote control signal can be received causing actuator to

energize.

3. STEP 3. Energize Open control to check operation of contactor and pushbuttons.

Open controls must move valve in Open direction. If valve Closes, actuator must

be stopped and any (2) two power voltage leads reversed to correct voltage

phasing.

CAUTION:

If voltage is improperly phased, Torque and Position Limit Switches are not in

circuit to protect valve.

4. STEP 4. Seal all eld conduit entries in accordance with National Electric Code.
